Conciseness

The body is mostly efficient and avoids explaining basic concepts, but sections like 'Common Rationalizations' and the extended ASCII dependency graph add length that does not directly teach Claude something it does not already know, and some scaffolding could be tightened.

Actionability

Provides fully concrete, copy-paste-ready templates for task structure, checkpoints, and the plan document, with explicit file paths and field-by-field structure covering the common cases.

Workflow Clarity

The 5-step planning process is clearly sequenced with explicit ordering rationale (bottom-up, vertical slicing) and a dedicated Verification section plus per-phase checkpoints forming validate/review feedback loops before implementation begins.

Progressive Disclosure

Content is well-organized into clearly signaled sections with a single one-level-deep reference (definition-of-done.md) resolved via a relative path, but most reference material is inlined rather than split into separate files, leaving minor organization gaps.

Specificity

Names the domain ('Breaks work into ordered tasks') plus several concrete actions (estimate scope, parallelize), but the actions are procedural-situational rather than a comprehensive list of distinct operations, leaving minor coverage gaps.

Completeness

Clearly states both what ('Breaks work into ordered tasks') and when (multiple 'Use when...' clauses), but the 'when' is a list of situations rather than crisp concrete trigger phrases, so it is good but not maximally explicit.

Trigger Term Quality

Includes natural user-facing phrases ('a spec or clear requirements', 'a task feels too large to start', 'parallel work is possible') that a user would genuinely say, though it omits some common synonyms and explicit trigger keywords.

Distinctiveness Conflict Risk

The planning/spec-decomposition niche is mostly distinct from implementation skills, but there is minor overlap risk with general task-management or build skills that also produce task lists.
